Available on:
Double buffered:
GET_HALLS returns the state of the hall sensors input into the chipset.
The returned word is encoded as follows:

GET_PHASE
Data/direction:
Encoding:
Axis acted on:
Available on:
Double buffered:
GET_PHASE returns the current commutation phase angle, expressed
as the # of encoder counts past the max. value of phase A (cosine of
angle 0). The returned value is a 16-bit integer with a range of 0 to
32,767. This command can be useful for diagnostic purposes, as well
as for amplifier calibration.
